I have access to my company's DTM page but there's no add new web properties link. Is there any prerequisite for adding new web properties?
Thanks for reaching out. Depending on which user group you are in you may not have access to create properties. To create new properties you would need to be an admin. There is a matrix of the user groups here: https://marketing.adobe.com/resources/help/en_US/dtm/t_create_group.html.
